RUNWAY FOR WINDOWS.

Application flled August 13, 192G..` Serial No. 128,992.

and adapted toA slide freelyvin the-,process of opening or closing.

It has for a further object the-production and use of sound-deadenmgrunways or channelsl of the character indicated, with special cushioningmeans, and with means au for -automatic adjustment to provide for For afurther o ect this invention contemplates the production of elasticrunways of the character aforesaid, capable of exerting relativelyincreasedlateral,pressure locally upon the surfaces of slidable windows,

windows of varying'thickness..

' and at the same time of reducing` the area of.

rictional contact between runways and windows, as compared with.structures heretofore Agenerally employed.

As a further 'object this invention contemplates and provides improvedmeans for re- -tarding the admission of moisture between runways andwindow. I

Vith the foregoing andother Objects in view the present invention willnow be hereinatter particularly described and set forth by the appendedclaims. i

In the accompanying drawings which form part of this application forLetters Patent, and whereon like characters indicate corresponding partsin the several views:

Figure l isa horizontal sectional view taken through one window frame,my improved runway, and a Jfragment of a sashless glass window inoperative relation;

Figure 2 is a transverse sectional view taken through the presentimproved runway or channel as anarticle. of manufacture detached; and

Figure 3 is a perspective view of a portion of onerunway or channel alsounattaehed.

Reference beinghad to the drawings and to the numerals thereon, '4indicaties the usual window or door frame of a closed vehicle such, forexample, as an automobile.

Countersunk in the frame 4 is the iinproved runway or window channel 5,secured in place by the usual, or any approved means.4

his runway or channel is made of a highly elastic material such asrubber, and is oi unitary construction, having a ybase portion 6 whichupon its under surface is longitudinally serrated as shown at 7. Thepurpose and eilect ot said serrations or corrugations 7,'upon the undersurface oi' base is that ot' forming a permanent and more etlicientcushion between the runway and its window frame, to prevent vibrationsand chattering,

which might otherwise result from the relative movement of said parts,during passage ot the .vehicle overrough and uneven road beds, at alltimes and particularly after the rubber, of which these runways arepreferably made, has become relatively hard with age. These corrugationsalso serve tolighten the structure as a whole, and assist in securing'itin\ its operative position.

Rising from the base 6 of these runways, and integral therewith, areoppositely disposed co-acting side walls 8, 8, normally of convergingform as shown, and each terminating at its upper edge in a continuoushollow bead 9 as best shown'by Figure 2.

` Crossing the bottom of the runway and enveloping both side walls 8, S,thereof, is

a suitable fabric coverinfY 10, which may be made otfelt, suede, ve vet,velveteen, or. any1 other flexible textile material, and whichpreferably extends down the outer sides of the walls 8, 8, toapproximately the base ot the structure, and is glued or otherwise.securely attached.

This being a description of the invention, its use and operation are soapparent that no further and detailed description thereof would seein tobe necessary.

A fraineless glass window such as` indicated in Figure 1 by the letterA, positioned within its runways 5, is capable of sliding freely in bothdirections. These windows are usually of plate glass, but even in plateglass there may be some variations as to thickness. This however, isfully provided for and compensated for, by the converging arrangement ofside walls 8, 8,and the oppositely disposed inwardly projectingcharacterv ot the hollow beads 9, S), upon the edges of said walls,serving also to absorb vibrations and to etliectually cushion the windwAlinall directions without undue friction.v c

rlhe foregoing being a description of one practical embodiment of mypresent invenpane.

tion, it should he understood that I do not consider myselfA limited tothe particular form and arrangement of parts' shown and described. Onthe contrary the substance of this invention as hereinafter claimed, iscapable of various modifications and changes in form and constructiondeparting from the spirit of the invention.

Having thus described I now claim Patent is:

1. A fiexible runway for windows having a base provided with a series otserrations upon itsunder surface, and also projecting side Wallsarranged and adapted to contact with opposite surfaces of a slidablewindow and desire to secure by Letters without in the least myinvention, what `Way having ed to contact with fabric covering Lemerre2. A runway for Windows formed of elastic material having longitudinalserrations covering its under surface, said runway also having sidewalls arranged and adapted to Contact with opposite surfaces of aslidable window pane.

3. A runway for windows Vformed of elastic material having longitudinalserrations covering'its entire under surface, Said runside wallsarranged and adaptopposite surfaces of a pane, and also having a for itsinner surface.

In testimony whereof I alix my signature.
